To all 'whom t may concern:

Be it .known that I, ARMAND H. PEYCKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful improvements in Methods of MakingReversible F ulcrums, of which the following` is a specification. y

lhis invention relates to a method of making reversible fulcrums.

The object of this invention is to simplify and improve the method ofmaking brake beam fulcrums.

This and other objects are accomplished by means of the method disclosedon the accompanying sheet of drawings, in which Figure 1 vis aperspective view of a blank used to form the strut of the brake beamfulcrum;

Figure 2 is a perspective view of the same blank after having beenstretched or elongated;

Figure 3 is a perspectiveview of the same blank after same has beenstretched an increased amount and provided with enlarged portions forstrengthening purposes;

Figure a is a perspective view of the same blank after the ends thereofhave been offset a given amount and the intermediate portion of theblank providedl with ai tension rod seat;

Figure 5 is a perspective view of another blank or lever supportingmember;

Figure 6 is a key for retaining the reversible lever supporting memberin one of a plurality of positions; and

Figure 7 is a plan view of the completed brake beam fulcrum.

The various novel features of the inven-V tion will be apparent from thefollowing description and drawings, and will be particularly pointed outin the appended claims.

Referring to the figures of the drawings, it will be noted that I first`provide a blank, preferably in the form of a steel bar 10. This bar isthen heated and subjected to pressure, whereby all parts, with theexception of the middle l1, of the blank are elongated. The blank isthen subjected to further treatment or pressure, during which theportions 12 and 13 of the blank are enlarged, the portions 13 beinglocated adjacent the middle portion 11 of the blank. The bar is thenplaced under a forge ham- I Speication ofgLettersPatexitf Patented.,Feb,r 192,2, 'application med. March 2o,"192o. *serial Nb. ceases.r

23, which retains the reversible lever sup vporting member 16 in aplurality of dif-k The blank 16 is then ap-l ferent positions. plied tothe formed blank 10,V so that the trunnion portion 18 is placed withinthe trunnion receiving portion 21 at the tension rodV end of the strut.The blank 10, or

rather the legs thereof, are then bent around the lever Y receivingmember as shown in Figure 7 of the drawings, the extremities 15 of thelegs being bent laterally, to be riveted in ak well known manner to thecompression member of the truss type of lbrake beam.

The key 23 is shown inserted to hold the y lever supporting member 16kin one of its positions. y.

It'will be understood that the lever receiving member 16 is rotatablymounted be-v tween the legs of the strut 24, making the fulcrumreversible.

It is my intention to cover all modifica tions of the invention fallingwithin the spirit and scope of the following claims.

I claim: l y 1. The method of making a fulcrum, consisting first inproviding a lever supportingvmember, then providing a blank, thenforming a tension rod seat intermediate the a ends thereof, and thenbending the blank intermediate its ends to form a strut eme bracing andrevolubly receiving the lever supporting member.

2. The method of making a fulcrum, consisting iirst in providing a leversupporting member, then providing a blank, then forming a tension rodseat and trunnion receiving portions therein, and then ,bending saidblank around said lever supporting member toform a strut.

3. The method of making a fulcrum, consisting first in providing a leversupporting member having trunnion portions, then providing a blank, thenproviding said blank with a tension rodseat and a trunnion receivingportion in the middle of said blank,
